[release/7.0.2xx] [tests] Allow a little bit of leeway when testing f…

…loating point numbers in SKTransformNodeTest. (#18173)

Fixes this test failure:

    MonoTouchFixtures.SpriteKit.SKTransformNodeTest
        [FAIL] EulerAngles :   #x1
            Expected: -2.14159298f
            But was:  -2.14159274f


Backport of #18157
